Sure, there are a few valid-ish reasons for why some individuals buy their pills over the Internet.

Certain drugs are cheaper in, say, Canada. Others can be embarrassing to ask a doctor for or pick up from the pharmacy, like, say, Viagra. There is also the ease with which otherwise difficult to acquire drugs can be illegally "prescribed" by over-the-Internet "MDs" and sent airmail to your home, no questions asked.

By this point, we should all be at least aware that spammy Web pharmacies are a money-sucking sham at best and a hugely dangerous and untrustworthy resource at worst.
